This is normal, expected behavior for Charmed Kubernetes. The kubernetes-master units do -not- participate as Kubernetes nodes or appear in `kubectl get nodes` output. This is because the kubernetes-master units run only the Kubernetes control plane components: kube-apiserver, kube-controller -manager, kube-scheduler. They do not run Kubelet.
